METHOD AND APPARATUS FOR MANAGING SECURITY STATE TRANSITIONS

摘要

A method and apparatus for managing security state switching device in the (security state transitions) is provided herein. During operation, the security token (security token) will indicate whether the device security state or non-secure state. The security token controls whether the verification image (image validation) and whether security is allowed access to the critical resources you want to happen. When made the transition to a non-secured state, the components to be regenerated (recreation) of the security token is removed and cut off from the non-secured state, thereby preventing the non-security code is spoofed (spoofing) a security status. In the non-secure state, the image verification is bypassed, is allowed to non-secure code is executed. If you re-generate the transition to security, the security token is recreated, all the images on the device are analyzed to determine whether they are approved.;
